Monodictys castaneae
Monodictys castaneae is a species of dematiaceous hyphomycete fungus in the genus Monodictys. It is a saprobic, lignicolous species producing dark, muriform conidia on decaying wood and bark. The species was originally described by Karl Friedrich Wilhelm Wallroth and later transferred to Monodictys by S. J. Hughes.
Description
Conidiophores are macronematous, mononematous, simple, short, and are brown to dark brown, arising directly from the substrate. Conidiogenous cells are integrated, terminal, and monotretic. Conidia are produced singly, dry, dark brown to black, thick-walled, broadly ellipsoid to obovoid, muriform, and typically with 3–7 transverse septa and several longitudinal septa. Conidia are rounded apices, truncate bases, and a roughened to verrucose surface.
